PALLET-FEEDER FOR MIOLD-DUMPING MACHINES.

Patented Dec. 24, 1918.

Original application fiIed March 23, 1915, Serial No. 16,371. Dividedand this application filed April 30,

To all whom it may concern Be it known that I, ARTHUR O. DUPUY, acitizen of the United States, and a resident of Cleveland, county ofCuyahoga, and State of Ohio, have invented a new and useful Improvementin Pallet-Feeders for Mold- Dumping Machines, of which the following isa specification, t -e principle of the invention being herein explainedand the best mode in which I have contemplated applying that principle,so as to distinguish it from other inventions.

The present improvements relate to palletfeeding mechanism for molddumping machines in general, and in particular for a mold dumpin machineof the character described in my co-pending application Serial No.16,371, filed March 23, 1915, now Patent'No. 1,227,76a out of whichapplication the subject matter of the present case has been divided. Tothe accomplishment of the foregoing and related ends, said invention,then, consists of the means hereinafter fully described and particularlypointed out in the claims.

The annexed drawings and the following description set forth in detailcertain mechanism embodying the invention, such disclosed meansconstituting, however, but one of various mechanical forms in which theprinciple of the invention may be used.

In said annexed drawings Figure 1 is a side elevation of the machine,and Fig. 2 is an elevation of a machine showing the other side.

The machine comprises a suitable frame built up of suitable members 1,in which there is rotatably mounted upon a horizontal axis a maindriving shaft 2. The molds when brought from the press, enter themachine upon a conveyor consisting of spaced rolls 5 mounted at theright end of the machine as shown in Fig. 1. The rollers 5 which arewithin the machine, are not driven, but are merely free to rotate, andthe mold box or mold 70 is stopped in the desired position upon theserolls by contacting a flange 13 attached to the frame. The mold is thenpositioned transversely of the machine and adjacent to the invertingmechanism. The conveyer for transporting the molds from the brick pressto the present Serial No. 165,644.

machine will cooperatewith the rolls 5 but is not here shown.

It is unnecessary to describe in detail the machine, as such machinesare, in general, well known and this specific machine is clearlydescribed in my co-pending application above referred to. It issufiicient to say that the machine is adapted to receive afilled moldbox bearing a pallet or thin metal plate on its open upper face, invertthe same, and lift the mold box from oft the bricks which remain on thepallet. The present invention is directed to mechanism forautomaticallyplacing a pallet upon the top of each mold box just prior to itsinversion.

The progress of the mold boxes through the machine is intermittent, andeach mold 1s stopped at frequent intervals. The first of these stopsleaves a mold box 100 on the rollers 5 in front of a pusher bar 6 androller 9, and directly beneath the pallet feeding mechanism. This latterdevice consists of pivoted links 10, each pivotally connected to one endof a bell crank lever or bracket 101, the other ends 102 of these leversbeing directed toward each other and serving to hold them between apallet 12, which may be manually or otherwise placed thereon at asuitable time.

The upper ends of the links 10 are connected to a rod 103 attached to anoscillatory shaft 104:, which may be connected to suitable drivingmechanism in the machine to cause it to rock and depress the links 10 inorder to swing apart the arms 102 and drop the pallet 12 therefrom uponthe mold box 100. For proper coil, eration with the other parts of themachine the arms 102 are preferably operated to drop the pallet slightlyahead of the mold, that is with the left edge of the pallet extendingslightly over the left edge of the mold box, but this is, of course, amatter of convenience only.

Obviously, the simultaneous swinging of the arms 102 will cause thepallet to drop flatly upon the mold box, while its position thereon canbe accurately determined by the position given the arms above the mold.Either manual or mechanical feeding may be employed for the palletmechanism.

Other modes of applying the principle of my invention may be employedinstead of the one explained, change being made as re ga-rds themechanism herein disclosed, provided the means stated by any of thefollowing claims or the equivalent of such stated means be employed.

I therefore particularly p0int out and distinctly claim as myinvention 1. In a mold-dumping machine, the combination of spacedmovable brackets adapted to receive a pallet therebetween, and meansadapted to actuate said brackets to release a pallet therefrom.

2. In a mold-dumping machine, the combination of spaced movable bracketsadapted to receive a pallet therebetween, and means adapted tosimultaneously actuate said brackets to release a pallet therefrom andpermit the same to fall in a horizontal position.

3. In a mold-dumping machine, the combination of cooperative pivotallymounted brackets adapted in one relation to hold a pallet therebetvveen,and means adapted to actuate said brackets to release a pallettherefrom.

4. In a mold-dumping machine, the combination of cooperative pivotallymounted brackets adapted in one relation to hold a pallet therebetween,connections between said brackets adapted to produce simultaneousmovement thereof, and means adapted to actuate said connections to swingsaid brackets and release a pallet therefrom.

5. In a mold-dumping machine, the combination of cooperative pivotallymounted brackets adapted in one relation to hold a pallet therebetween,extending lugs on said brackets, arms pivotally connected to said lugsand to each other, and means adapted to actuate said arms tosimultaneously swing said brackets and release a pallet therefrom in ahorizontal position.

Signed by me, this 28th day of April, 1917.

ARTHUR O. DUPUY.
